Setting the Units of Measurement
|
55
Each type of measurement (e.g., linear, angular, etc.) has its own precision
settings. These settings control how AutoSketch formats numbers for output.
Regardless of these precision settings, AutoSketch always performs all
calculations at the maximum possible precision.
Setting the International Units of Measurement
AutoSketch lets you set the default measurement system for Windows from
within the program. You can set AutoSketch to use English or Metric units,
place leading zeros before decimal values, and format decimal numbers using
a comma instead of a period for the decimal separator.
To set the international units of measurement
1 On the Tools menu, click Drawing Options. The Drawing Options dialog
box appears.
2 Click the Units page tab.
3 Click a method from the Measurement System drop-down list box.
4 (optional) Check the Show Leading Zeros check box.
5 (optional) Click the Period or Comma option button in the Decimal
Symbol section.
6 Click OK.
Setting the Linear Units
AutoSketch allows you to choose from nine standard units of measurement
for lengths. Six are English measures and three are Metric. You can also
specify the precision AutoSketch uses to display decimal and fractional linear
values separately. The choices for decimal precision range from 1 to
0.0000001, while the choices for fractional precision range from 1 to 1/128.
To set the linear units of measurement
1 On the Tools menu, click Drawing Options. The Drawing Options dialog
box appears.
2 Click the Units page tab.
3 Select the units of measurement from the first drop-down list box in the
Length section.
4 (optional) To set the decimal precision for linear measurements, select a
value from the Decimal Precision drop-down list box.
5 (optional) To set the fractional precision for linear measurements, select a
fraction from the Fractional Precision drop-down list box.
6 Click OK.
